5:30-6:30 most evenings. It has gotten earlier as we've aged. (Back in the days when I worked in advertising, I often didn't get home until 6:30 or so, and it was not unusual for us to eat at 8.) When the cat was diagnosed with diabetes and put on insulin, we tried to keep him on a regular schedule that fit best with us, so that meant earlier dinner for us so he could eat and get his shot shortly after we had finished. He is now in remission, but we've kept the same schedule.
During the pandemic, when we finally began to go out to a handful of places, we would go between 4:30 and 5 in order to get there, eat and be gone before it got busy.
